Abstract:Data aggregation based on compressed data collection need efficient routing forwarding tree protocol to gather the coded data corresponding to the sensor nodes to the sink node effectively. A new distributed compressed data collection method with high efficiency and energy saving is presented. Each sensor node can be found alone in the part of its parent and able to build a routing tree, without using the center node to build all forwarding tree, which allows each sensor node to make local decisions on the forwarding tree construction and maintenance. Simulation results show that the complexity of the new method is lower compared with that of the traditional method, and the cost reduces nearly 50%.
